I think you may have heard about some applications that extend the standard email protocols like Spark or some other email clients (that's just an example --I know it's not available for Linux). In that case, you may be OK just by carefully reading the privacy policy, as they may need to centralise in their server the email fetching to then deliver it to you (e.g.: snooze emails, delay sending even without you having to have the client app open, etc.). Those functionalities would have you setting your email credentials in their server, but that doesn't mean that they wouldn't protect them. As with everything, the best is to read ToC and Privacy Policies.It seems to me like the services could steal your password through the application or something. Is this the case? Are there any risks in using it?
im a claws mail man ; using bogofilter for spam which gets email from gmail. Last time i had to set iy up theres a handy function to re-create tree file structure that is on gmailThunderbird and Seamonkey are good email client.
Seamonkey is an browse and email client. The good detail is that use much less RAM than Firefox and is possible change several settings in propertis where Firefox not allow being only possible using about:config.
Using Thunderbird and using internet all time you need FIrefox and Thunderbird in RAM and will use more RAM. Seamonkey is both browse and email client and will use less RAM and the only problem is some few sites displaying false warning that the browse not is Firefox being easy to fix it.
When changing OS or formating even saving Thunderbird or Seamonkey email folder not is simple to copy to new installed system if you not copy totally the profile folder and if you download all email to computer and deleted in email server caution you will have problems that can be fixed if installing plugin importexporttools that you select the previous email folder and copy totally to new email folder.
Need say again ... caution if downloaded all emails and deleted all in email server and done an partition format.
